Replacing a boiler is a significant home improvement project, and is one that can vastly improve your home’s heating efficiency and overall comfort.
Whether you’re dealing with an ageing system that’s no longer reliable or looking to upgrade to the latest in heating technology, knowing how long the replacement process will take can help you plan accordingly.
This article aims to give you a clear understanding of the timeline involved when replacing a boiler.
Factors influencing replacement time
The replacement time for a boiler can vary based on several factors, making each installation unique. Here’s a closer look at what can influence the duration:
- Type of boiler: The kind of boiler you’re installing – whether it’s a combi, system, or regular boiler – plays a major role. Combi boilers, which combine heating and hot water systems into one unit, may be quicker to install than system or regular boilers, which require separate components like cylinders and tanks, and the extra pipework and support structures, as well as access to tricky areas.
- Complexity of existing system: If your current central heating system is outdated or complex, it may take longer to integrate a new boiler. Older pipework, in particular, may need to be upgraded or modified to ensure compatibility with a modern boiler.
- Additional work: If additional tasks need to be completed, such as flushing the system, moving radiators or upgrading the controls and wiring, this will extend the installation time.
Pre-replacement steps
Before the actual installation begins, several preparatory steps need to be taken. These steps ensure the replacement process goes smoothly and includes. First, there’s the consultation and survey. This is where a professional heating engineer visits your home for an initial consultation and system survey. This can take anywhere from 1–2 hours. The engineer will assess your current boiler and heating system, discuss your needs, and recommend the most suitable new boiler. After the survey, you’ll receive a detailed quote outlining the costs and timeline. Once you’ve agreed, you’ll schedule an installation date.
The replacement process
Once all the preliminary steps are completed, the actual replacement process begins. Here’s a breakdown of what you can expect.
Preparation (0.5–1 day)
The first stage involves preparing your home and the existing system for the new boiler. The installer will:
- Power down the system: Shut off the relevant water, gas and electricity supplies to ensure safety.
- Remove the old boiler: This can take a few hours, depending on the system’s complexity.
- Modify the space: If necessary, the area where the new boiler will be installed might need modifications to ensure it fits properly. This could include adjusting shelving or pipework, or other elements such as knocking out or building up masonry.
Installation (1–2 days)
The core of the replacement is the installation itself. This involves:
- Positioning the new boiler: This is where the new boiler unit is put into the designated space and secured in place.
- Connecting to existing systems: Linking the new boiler to the existing plumbing and heating system. This can take longer if new components or modifications are needed.
- Installing new components: If you’re upgrading any system parts (such as radiators, thermostats, expansion tanks etc.), this will be done at this stage.
Complications can arise, like dealing with tight spaces or outdated systems, which can sometimes extend the installation time.
However, experienced installers can usually navigate these challenges efficiently. Obvious issues should have been uncovered at the survey stage, so they’ll already be factored in.
Testing and commissioning (0.5–1 day)
After installation, the system needs to be tested to ensure it’s working correctly:
- Testing for leaks: The installer will check all connections and joints for any leaks, and fix any that need doing.
- Pressure checks: Ensuring the system pressure is within the recommended range.
- Commissioning: The engineer will conduct a series of tests to confirm the boiler operates efficiently and safely.
Once all tests are passed, the engineer will commission the boiler, officially bringing it into service. They will also take this time to explain the new system to you, including how to operate the thermostat and any connected smart controls.
Possible delays
While every effort is made to ensure a seamless process, sometimes delays are unavoidable. Common causes include:
- Unforeseen complications: Discovering unexpected issues like additional repairs needed on existing pipework or radiators.
- Delivery issues: Delays in receiving the new boiler or components from the supplier or manufacturer can extend the timeline. Major traffic issues can also disrupt delivery on the day.
- Additional repairs: Sometimes, during the installation, it’s found that other parts of the heating system need attention, such as leaks or blockages that weren’t initially apparent.
A reputable installer will keep you informed of any delays and work to resolve issues promptly, minimising the impact on your schedule.
Costs vs. time
The cost of the installation can also play a role in the timeline. Opting for a more complex system or additional services may extend the installation period. Remember that this can offer better long-term benefits, such as improved efficiency and energy savings, so don’t rush to have it installed too quickly; an extra half day could be of huge benefit. Indeed, paying more for faster services can sometimes reduce the overall time but make sure this doesn’t compromise the quality of the installation.
Aftercare and maintenance
Once your new boiler is up and running, your attention shifts to maintaining it to ensure longevity and optimal performance:
- Post-installation services: Most installers offer a post-installation inspection after the first year to ensure everything remains in good working order.
- Regular maintenance: Routine maintenance checks help to catch potential issues early and keep your new boiler running efficiently. Many companies offer service contracts or maintenance plans for added peace of mind. Your boiler’s warranty will probably demand at least one annual service by a qualified heating engineer. Regular servicing is vital to extend the boiler’s life and maintain its efficiency, ultimately saving you money and preventing future issues.
